Ethanolic Leaf Extract

Byrsocarpus coccineus is an indigenous herb widely dispersed in tropical Africa and commonly known as Crimson thyme. The leaf and root of the plant is noted to possess medicinal benefits in traditional medicine of the Western part of Nigeria. The plant has been reported to possess analgesic, antiplasmodial, inflammatory, antidiarrhic and antipyretic activities. The present study was therefore aimed at determining the sub-acute toxicity of ethanolic leaf extract of Byrsocarpus coccineus. The ethanolic leaf extract of the plant was administered orally at 250, 500, and 1000 mg/kg to three groups A, B and C of Wistar rats respectively for 14 days while the control group D was administered orally with 3ml/kg of distilled water. Blood samples were then obtained from the anaesthetized rats for haematology and serum biochemistry. The result obtained from serum analyses showed a significant increase (p<0.05) in the levels of blood urea nitrogen and creatinine levels while the increase in alkaline phosphatase is not significant for the treated groups B and C compared with the control. It was therefore concluded that high doses of the extract may have untoward effects on the kidney and therefore, the use of the plant extract in high doses should be discouraged.

Ethanolic Leaf Extract

Hypertension is a risk factor for a variety of morbidities, especially stroke, myocardial infarction, and the development of congestive heart failure, as well as death. Several treatment options are used for treatment of hypertension; however, a lot of short comings have been associated with them. In order to proffer a possibly better and cheaper means of preventing hypertension, this study aims at investigating the antihypertensive and cardio-protective effects of the ethanolic leaf extract of Mucuna pruriens. Thirty-six male albino rats were used for the study. Oral administration of 8% salt diet was used to induce hypertension which significantly increased blood pressure and oxidative stress in the hypertensive animals compared to the control group. The phytochemical screening of the extract was carried out, the weight of the experimental animals was monitored, hematological indices was assessed, and systolic and diastolic rates were evaluated at different concentrations of the extract. The screening indicated the presence of tannin, saponins, flavonoids, terpenoids, and phenols while reducing sugars, cardiac glycosides, glycoside, alkaloids and steroids were absent. The weight of the liver of rats given standard drug, 150 mg/ml of the extract, 250 mg/ml of the extract and untreated groups were significant lower (p<0.05) when compared with the control group while the group administered with 100 mg/ml was higher.

Diclofenac is used to treat rheumatism disorders, which are associated with the damages of renal, gastric and hepatic organs. Diclofenac is a pharmaceutical drug that is known to induce toxicity on its overdosage and long-term usage. Madhuca longifolia is known to have antioxidant, anti-inflammatory and anti-ulcer activity. It is an evergreen tree that is reported to have many ethnomedicinal uses. The other properties of Madhuca longifolia include anti-diabetic, analgesic and anti-microbial activities. Our study aims to evaluate the pre-treatment activity against the diclofenac-induced toxicity by the Madhuca longifolia aqueous leaf extract in Wistar albino rats for 10 and 15 days. Rats were divided as Group-I: Normal control, Group-II: Diclofenac on the last two days, Group-III and group-IIIa: Diclofenac + Aqueous Leaf Extract of Madhuca longifolia, Group-IV and group-IVb: Diclofenac + Silymarin, Group -V and group-Va: Aqueous Madhuca longifolia leaf extract. After the sacrifice, the rats were studied for antioxidant assay, renal enzyme markers, liver enzyme markers, and histopathological analysis of the kidney, stomach, intestine, and liver. As a result, we could identify that Madhuca longifolia has reduced the toxic changes in rats caused by diclofenac.

Tetrapleura tetraptera stem bark has been reported to cause inhibition of luteinizing hormone release in cultured rat pituitary cells. Hence, we investigated the effects of Tetraptera tetrapleura pod extract on follicle stimulating hormone, luteinizing hormone, cortisol, progesterone and estrogen. Thirty non-pregnant female wistar albino rats were divided into group A - D. Group A rats were used as Control. Group B rats were administered 1 mg/kg/day of clomiphene citrate orally. Group C rats were administered 200 mg/kg of extract only, whereas group D rats were administered 1 mg/kg /day of Clomiphene citrate plus 200 mg/kg of extract. At the end of 14 days experiment, group A, B and D were found in proestrus phase and group C in diestrus phase. FSH and cortisol levels remained unchanged. Group C and D rats produced significant reduction (P < 0.05) in LH and estrogen levels in prolonged proestrus and normal diestrus respectively. Progesterone level was significantly high (P < 0.05) in the group C rats. The reduced LH level could be due to the anti-estrogenic effect of extract during proestrus when LH secretion is expected to surge. But co-administration resulted in high progesterone secretion, suggesting extract may have influenced progesterone secretion in group D rats simultaneously administered with clomiphene citrate and extract. The above findings indicated that Tetrapleura tetraptera pod extracts inhibited luteinizing hormone and estrogen even when co-administered with clomiphene citrate.

Ethanolic Leaf Extract

Cadmium is a well-known environmental pollutant that has been proven to be nephrotoxic and hepatotoxic in the body. In this study, the effect of ethanolic leaf extract of Irvingia gabonensis (O’Rorke) Baill (IG) against cadmium-induced nephrotoxicity and hepatotoxicity in Wistar albino rats was investigated. 30 female wistar rats of weights between 98-153g were grouped into 6 groups of 5 animals each. Group 1 served as the control and was placed on rat feed and water. Groups 2, 3, and 4 were administered 10mg/Kg body weight (mg/kgbw) of cadmium chloride (CdCl2) only,10mg/Kgbw CdCl2 and 200mg/kgbw extract, 10mg/Kgbw CdCl2 and 400mg/kgbw extract, respectively. Groups 5 and 6 were given 200mg/kgbw and 400mg/kgbw of IG extract respectively and the treatments lasted for 28 days. Results obtained revealed significant (p<0.05) increases in the serum levels of all renal and liver function biomarkers in group 2 (CdCl2 only) as compared with the control. There were however significant (p<0.05) decreases in the serum levels of the assayed parameters when groups 3 and 4 were respectively compared with group 2. It can therefore be concluded that ethanolic leaf extract of Irvingia gabonensis (O’Rorke) Baill enhances the integrity of the kidneys and liver of cadmium-induced wistar albino rats.

Ethanolic Leaf Extract

The purpose of the present study was to evaluate the laxative and antimicrobial activities of ethanol extracts of leaf and root of Amaranthus viridis L. The laxative activity of ethanolic leaf extract of A. viridis was studied using six groups of wistar albino rats; Group I which served as the negative control received 0.5ml/kg of normal saline, Group II received 10mg/kg of Dulcolax and the rest of the groups (III-VI) received 400, 200, 100 and 50mg/kg of the extract respectively. The laxative activity of the ethanolic leaf extract was expressed as the mean of total weight of faecal output in each group. A significant (p<0.05) dose dependent increase in the faecal output was observed at the 200mg/kg (3.00 ±1.41gm) and 400mg/kg (3.50 ±2.12gm) doses compared with the negative control. The antimicrobial activity was expressed as the diameter of the zone of inhibition hence the minimum inhibitory concentrations were determined. The antimicrobial activity of the A. viridis leaf and root extracts had dose dependent increases in all the tested organisms from their various minimum inhibitory concentrations (MIC). The result confirmed that the leaves and root of A. viridis possess laxative and antimicrobial activity.
